I recently was playing the 909D3 with a axivcore tour green 76x. I will be getting or ordering the new 913 but was wondering about shafts. The place where i go to do my fitting does not have any shaft heavier than a mid 70's weight. They have the diamana in the mid 70g and the phenom also at the weight. I would like to possible jump up the the mid 80 to tame my very quick transition in my swing. Judgeing for my old shaft would i stay in the x flex range if i jumped up 10grams or if you go up in weight do you want to also tame the flex. My ss is 115-117. i did like the 76x but was wanting a little heavier to tempo my transition. was thinking the ahina or phenom or rip all in the mid 80g. which shaft also is a good fit.
